Tenet Arca Plasmor Guide & Build

Hello everyone,

My name is UltimoFive and today we are going over the [Arca Plasmor], The Boomstick. I thought it would be nice to take a break from Kuva weapons, so here we are.

This build does a heavy amount of damage to large crowds and easily kills crowds up to level 70 for Grineer & The Corrupted, while easily killing crowds up to level 135 for Corpus and Infested.

Weapon Information

• The [Arca Plasmor] is obtained from the Energy Lab in the dojo and requires these materials to make it.
  

• The Arca Plasmor has a mastery rank of 10.

• The [Arca Plasmor] comes with 3 "V" polarities and because of this the build only requires 4 forma.

Advantages Vs. Disadvantages

Advantages:

• High Critical Chance

• Very High Status Chance

• Innate 3 meter punch through

• Shots have a guaranteed Impact Proc to enemies up to 15 meters

Disadvantages:

• Innate Radiation Damage, no Physical Damage

• Has linear damage falloff from 100% to 33.33% at 10 meters to 20 meters

• Limited range of 30 meters

• No Bonus damage on headshots

• Lowest fire rate of all shotguns

Builds

Corpus:

The Arca Plasmor is mainly efficient against the corpus due to its innate Radiation damage and Impact procs. Magnetic/Toxin is really good against the corpus, but takes a slight hit to killing efficiency of high tier robotic enemies such as Bursa. Magnetic helps with deleting shields, while toxin helps with flesh damage of the human corpus.

Infested:

The elements used against the Infested are going to be Corrosive/Heat. Corrosive helps against the fossilized enemies, while Heat just annihilates Infested Flesh. This build however is still effective on Deimos due to the weapons innate radiation damage.

Corrupted/Grineer:

I am putting these two factions together for the purpose of their build and how efficient this weapon is against them. The elements used against these factions are going to be Viral/Heat. Viral helps by amplifying damage to health, while the heat helps with stripping armor, BUT due to the nature of this weapon it can hardly keep up while dealing with Alloy armor. It's just to slow and due to it being inefficient with corrosive stacks it just isn't a good choice to take this weapon against Grineer or the Corrupted over level 70.

Recommended Alternative Mods

• Chilling Reload - In place of Chilling Grasp for the Grineer, and Corrupted builds. Due note that this will affect the damage in turn for reload speed.

• Incendiary Coat, Chilling Grasp, and Contagious Spread - In place of Viscous Spread if you can't handle the spread, but due to Hell's Chamber the effect of Viscous spread isn't as bad, but noticeable. To be noted you will lose damage.

• Charged Shell - If you don't have Primed Charged Shell

• Point Blank - If you don't have [Primed Point Blank]

Try to stay around 44.8% Status Chance, it makes it so you are practically guaranteed at least one status proc, other than the guaranteed impact proc.

Non-Recommended Alternative Mods:

• Any Critical enhancing mods - Yes the Critical Chance is high, but not enough to matter unless you have a critical Riven. Due to this build you are almost always getting one crit per shot.

• Frail Momentum - Shotgun Spazz is more than enough fire rate for this weapon, honestly it sucks...
